Improved clothes-wringer



UNITED STATES E. M. STEVENS, OF BOSTON, MASSACHUSETTS.

IMPROVED, CLOTH ES-WRINGER.

Specification forming part of Letters Patent No. 35,115, dated April 29, 1862.

To LIZ whom t may concern.:

Be it known that I, E. M. STEVENS, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Machines for XVring-ing Clothes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a front view, Fig. 2 an end view, and Fig. 3 a transverse section, of one of the rolls.

Like parts are indicated by the same let ters in all the drawings.

The nature of my invention consists, iirst, in making the levers F F jointed or in two parts, F F, and providing the same with thumb-screws 7i, whereby more or less pressure maybe readily given to the axle of the roller C, as may be required in wringing clothes of different body or thickness; second, in making` the core lV, Fig. 3, of the rolls tluted and iittinginto the flutes cylinders of rubber, r, surrounded by a hollow rubber cylinder, It, and alsoY in vulcauizing the rubber upon said core, whereby the rubber is made to adhere more securely to the core than it could otherwise be made to do, while at the same time, owing to the open spaces s, more elasticity is obtained from the same amount of rubber; and, third, in constructing the lever-clamps Kol. a clothes-ringing machine with self-mljusting feet N, so as to t the sides of any tub whatever its thickness and whether uniform or not, and thus by present ing a large smooth surface to the outside of the tub prevent the same from being indented or marred.

To enable others skilled in the art to make and use my machine, I will now describe its construction and operation.

A A are the upright parts of the frame, which are coin'iected by means of the curved slat A', Fig. l, at the top and the slat B', Fig.

'2, on the back.

B is the inclined board for conducting the water into the tub.

D is the lower cylinder, one extremity of whose axle d passes through one of the uprights A and is provided with a crank, E, the other extremity entering the opposite upright, as represented by the dotted lines in Fig. l.

C is the upper cylinder, the ends of whose axle c turn in longitudinal slots in the uprights A A. This cylinder C is made to press upon cylinder D by means of the springlevers F F, which turn on fulcra j j in slots in the frame A A, the short ends of the levers, as represented by the dotted lines in Fig. l, bearing upon the axle c, while the upper ends of the levers are drawn toward each other by means of the spiral spring I. By raising the axle c of cylinder O it is obvious that the upper ends of the levers F F will be thrown farther apart, and the stiffer the spring I the harder the cylinder C will be pressed upon the cylinder D. It is also evident that in wringing very thick and bulky articles the upper cylinder should be allowed to rise farther from the lower than in wringing articles less in thickness and bulk, and in order to readily adjust the pressure to the various kinds of clothes to be wrung or passed between the cylinders I make the levers F F in two parts, F and F, F being mort-ised to receive the tenon f, forming the upper half of F, as represented by the dotted lines in Figs. l and 2. The two halves F and F are united by means of pivots g.

h 71 are thumb-screws passing through nubs on the outer edges of F into the mortises till their ends rest against the tenons f, as represented by the dotted lines in Fig. l, by means of which screws it is obvious that the upper ends of F F may be brought nearer together or farther apart at pleasure, and thereby more or less of tension given to the coil-spring I.

The core I (see Fig. 3) of the cylinders C D is iuted, and in the iiutes are placed tubes or solid cylinders of rubber, r, before it is vulcanized, and encircling these is a tube of rubber, R, thus leaving the spaces s between the core XV, cylinders r, and tube R. After Y the rubber is placed in the proper position on the core it is vulcanized, and by that means the core and the rubber are very closely and rmly united. The utility of the spaces s has been mentioned above.

K K are the lever-clamps, (the shape and position of which are shown in Figs. l and 2,) turning` on the fulcra Z Zin the metallic pieces L, which are attached to the uprights A A by means of screws.

M M are thumb-screws passing' through the upper extremities of the levers K, and m m are metallic disks embedded in the Wooden. uprights for the ends of the thumb-screws to bear against.

N N are the self-adjustingfeet or clamps, constructed as shown in Figs. l and being attached to the tenons on the lower extremities of the levers K K Vby ineans of pivots n fn.. The inside of these feet is a little concave, so as to conform more nearly to the cxterior side of a circular tub.

Frein the above description it is plain that the inner face of the 'feet N Will bear liat and irin upon the side of any tub (as X, repre' sented by dotted lines in Fig. 2) Whatever' its thickness or whether the saine be uniform or not, thereby preventing' the tub from being,l

` tlninnb-screws 7L 71., substantially as set VForth,

and for the object specified.

MakingI the core Y of the rolls iluted and iitting into the ilutes cylinders of rubber, fr, surrounded by a rubber tubing, R, substantially as and for the objects specified.

3. The combination and arrangement of the lever K, self-adjusting foot N, and thn1nbscrew M, substantially as described, and for the objects specified.
